    Studies on Epidemiology, Therapeitics and Impact Analysis of Udder Health kit in Bovine Mastitis
    (ANDUAT, Kumarganj, Ayodhya, 21-07-11) Singh, Satyavrat; Singh, Jitendra pratap
    The present study was designed to evaluate the status of mastitis in buffaloes in this part of Eastern Uttar Pradesh with emphasis development and efficacy assessment of indigenously developed udder health kit. Overall prevalence of mastitis was 47.41% with prevalence of subclinical mastitis (37.78%) much higher than clinical mastitis (9.63%). A significant correlation (p< 0.01) was recorded between udder hygiene score and status of mastitis. The prevalence was least in the animals supplemented with nutritional supplements like mineral mixtures. Significant correlation was also observed in teat health scores, somatic cell count and mastitis status. The antibiotic sensitivity revealed sensitivity to Tetracycline, Gentamicin, Enrofloxacin, Pencillin and Streptopenicillin. Methicillin resistance was reported in 30.77% S. aureus isolates. Multiple drug resistance was observed in this study. Teat health was mainly addressed and the specific strains of major organisms were identified on the basis of molecular characterization. The antibiogram plants namely Neem (Azadirachta indica), Guava (Psidium guajava), Lemongrass (Cymbopogon citratus), Mango (Mangifera indica), Tulsi (Ocimum sanctum) and Seasum (Dalbergia sissoo) leaves revealed that S. aureus isolates were 100% susceptible to aqueous extracts of only Neem and Guava in addition to standard drug Streptopenicillin followed by Lemongrass that showed 60 % sensitivity. In vitro activity of 07 common essential oils namely clove (Syzygium aromaticum) oil, lemon grass (Cymbopogon citrates) oil, neem (Azadirachta indica) oil, moringa (Moringa oleifera) oil, coconut (Cocos nucifera) oil, turmeric (Curcuma longa) oil, eucalyptus (Eucalyptus globulus) oil were studied. The relative percent inhibition recorded highest for lemon grass oil against S. aureus was 65.09%. For clove oil and neem oil the percent inhibition was recorded maximum in whole milk culture as 54.98 % and 7.10% respectively.
